Abrasive Blasting
▁▁▁▁▁▁
Introduction
Abrasive blasting is a finishing process where a media is propelled at a high velocity against a part's surface to smooth or roughen it, or to remove contaminants, often in preparation for painting or another finishing process.
Although commonly referred to as sandblasting, blasting media with different abrasive properties may be used depending on the desired result. Media types include sand, metal shot, plastic or glass beads, walnut shells, baking soda, and even dry ice.

Design Considerations
✔ Masking or plugging is available for areas with tight tolerances.
✔ Complex, fine and intricate geometries may be difficult to blast evenly.
✔ Thin walls should not be blasted, for risk of deformation.
